M1 Mac Mini With LG 4k Monitor

I have an M1 Mac mini connected to a LG 32UD99-W monitor with a USB-C cable. Sometimes the screen doesn't wake up from sleep. Recycling the monitor power gets the display back, but the USB ports on the monitor stop working and doesn't show up on the System Profile anymore. I have a Blue Yeti mic connected and it doesn't light up when this happen. Rebooting the Mac mini fix all the problem.
I think there is something different with the USB implementation on the M1 Mac. I also have an NVMe to USB-C enclosure that works intermittently with the M1 Mac while works perfectly with other Mac. I hope this got sorted out soon.

Will a Apple thunderbolt display work with the new Mac Mini ?
i take it will with the thunderbolt 3 to 2 adaptor.

I see the same thing on my 32UK550B. However, don’t forget the following;
If you select 2560x1440 as a scaled resolution (with HiDPI), the image has to be rendered at 5K before being downscaled and sent to the monitor.
In my case it says it’s a 27 inch monitor instead of 32 inch, but I don’t think the mentioned 5K resolution is a fault. It’s not communicated in a clear manner though 😀.
Have you tried a USB-C to HDMI cable (rather than using a USB-C to HDMI adapter and then an HDMI to HDMI cable)?
The Thunderbolt Display via the TB2-3 adapter works fine on my M1 MacBook Air so I wouldn’t expect any problems.
This is such a coincidence, I have the same monitor and I am also waiting for M1 Mac mini. I will know on Dec 4th if there are any issues. I shall keep you posted.
I have bought 3x MBP M1s to connect to the LG 27UK850. Same issues with washed out colour via USB-C. So frustrating as it appears to be a bug related to the new Macs and my whole studio is full of these displays. Don't want to buy Intel machines for obvious reasons, so this is a major issue for me 
What exactly is this washed out color issue? Can you share a video pleaseI have bought 3x MBP M1s to connect to the LG 27UK850. Same issues with washed out colour via USB-C.

I'll try - you need to see the screens side by side which I can't do today. Basically the colours are much less intense than they should be and it seems to skew the colours somehow. Tried everything to correct it but nothing works so far.
Does this happen if we use hdmi cable as well? Or happens only with thunderbolt one
Not sure yet - the problem is that you lose the USB hub functionality by doing that of course, so it's much less convenient
Sorry to tag you again, but how's things at your end now? All working fine?
Sorry I am a bit worried that's why
Why aren't you using the Thunderbolt 3 direct connection on the LG 32UL950-W monitor instead of HDMI?
Quick update: it appears to solve the problem if you disable True Tone display in system prefs... tried it on two different MBPs and both worked fine over USB-C after. Can anyone else confirm?
🤦🏻♂️ hadn't thought of that! Night shift? It def seems to be working on the MBP for me
